摘要
Abstract
Aqua regia was used to dissolve the sample,Tl190.856nm was selected as the analysis line,and the inductively coupled plasma atomic emission spectrometry(ICP-AES)was established,the thallium mass concentration was in the range of 0.0020%～0.050%,and the spectral line intensity showed a good linear relationship,the correlation coefficient r was 0.99999,and the detection limit of thallium was 0.0076μg/mL.The test method is applied to the determination of thallium in zinc smelting materials,and the relative standard deviation RSD of the results is less than 4.62%,and the recovery rate is 90%～103%,which can be used to efficiently and simply determine the determination of thallium content in zinc smelting system.关键词
